Jennifer Aniston and Justin Theroux: Wedding on Hold?

Ten months after her engagement to Justin Theroux, Jennifer Aniston seems to be no closer to saying “I do.”

As fans eagerly wait for her to become Mrs. Theroux, multiple sources tell PEOPLE that plans for the much-anticipated nuptials have slowed down.

A few months ago, arrangements were in full swing, says a source who speaks to Aniston often. “Wedding bands were designed and Jen was deciding on a dress,” says the source. The actress had a date in mind, too – this spring.

Now, with both Aniston, 44, and Theroux, 41, overloaded with work commitments and a massive house renovation, “wedding talk has stopped.”

Both stars have signed on for acting projects in the coming weeks, and construction delays hampered the redesign timeline for the couple’s $21 million estate in L.A.’s Bel Air neighborhood. “There are other priorities [besides marriage],” says a source who knows the couple professionally.

With their packed schedules and the challenges of combining their lifestyles, “they need to figure out a way to create a life that makes them both happy,” says the first source. Still, “Jen can’t wait to be [Justin’s] wife.”
